This invention relates to improvements in a plurality of angular or L-shaped fluid fluid-circulating plates, such plates being circulating channels composed of parts or particularly employed in hydraulic presses branches 16, 17. The branches 16 of these for vulcanizing and similar uses. l channels are substantially parallel with one I One of the obfects of the invention is another and are drilled from one edge of 60 to improve the construction of such plates the plate toward the opposite edge, while with a view of obtaining an unrestricted the companion branches 17 are likewise parcirculation of water, steam or other fluid allel with one another and drilled from the therethrough and thus rendering them more adjoining edge of said plate toward the ellicient in operation. opposite edge, the inner or closed ends of 65 Another object is thc provision of a chancompanion channel-branches communicating neled or ported plate of this character havwith each oher and meeting approximately ing simple and inexpensive means for plugon a diagonal line drawn from the lower ging between the channels at predetermined left hand corner to the upper right hand points to cause a proper diversion of the corner of the plate, as shown in Fig. 2. 70 circulating fluid in a more or less circuitous 1n other1 words, the branches of the angular course through the entire area of the plate. channels are of progressively increasing A still further object of the invention is length from one corner of the plate toward to provideV a fluid circulating plate which the diagonally-opposite corner.

The circulating plates, desigwith respect to those located at the side nated generally by the numeral 15 and of edge of the plate between the channelwhich three are shown, are applied to the branches 16, whereby the fluid is compelled upper and lower cross heads in the usual to take a sinuous course, as indicated by manner and the. intermediate one is susthe arrows shown in said figure. Leading 105 pended from the customary guide rods 15a. into the outermost or longest channel is a In the preferred embodiment of the influid inlet 23 and opening into the innermost vention shown in Figs. 1-4, inclusive, each or shortest channel is a fluid outlet 24. A plate 15, which is rectangular in plan, is tubular member or sleeve 25 extends across made of rolled steel and is provided with the passage 20 into such innermost channel 110 Cil plate is a. very simple and for plugging the corresponding end of said passage.. This sleeve is provided in the sidethereof facing the companion passage 19 with a port 26 through which some of the fluid is discharged after being circulated "through the plate, as .indicated by the arrows in Fig. 2.

As shown in Fig. t, the filler pieces or plugs 22 which cause the proper diversion oit the fluid through the circulating channels may be somewhat larger in diameter than 'thielatter and Iare inserted in corresponding drilled openings or sockets 27 having internally-tlneaded'counter-bores 28 for receiving set screws 29 which hold the plugs in place. The latter `'are preferably constructed ot brass or other non-corrosive instal.

By this rarrangeinent ot' the fluid-conducting channels and connecting passages, they eftectually cover the entire area of the plate This method 'oit drilling the circulating inexpensive one andfresults in an absolutely tree How of the fluid through the circulating channels. Furthermore, the method of plugging e- `tweenthe'channels to cause the diversion of the fluid in a sinuous course over the entire plate-area 'is exceedingly simple and the plugs v18, 2l and 22 are readily removable to permit oit' thoroughly cleaning out the channels, whendesired.

:In the niodied forni of the invention shown in Figs. '5 and 6, the plate 80 is provi'de'd'wit'h a .plurality of parallel circulatingchannels 3l formed by drilling through the plate from on-e edge thereof to the opposite ledge and closed at their ends by suitable screw plugs 32. At their ends, these chan- Y nels are intersected by passages 33 closed at their ends by screw plugs34. Extending -across these passagesV in the alternate spaces between the circulating channels are iller pieces or plugs 35 held in place by set screws y`36. The filler pieces in the one passage are staggered with respect to those in the other passage, whereby the fluidis caused -to be `circulated in a sinuous course indicated by the arrows in Fig. 5. The oiiterniost chann'el Slat one side ot the plate has afluid inlet 37 while the corresponding channel at the 'opposite side of the plate has a 'fluid oui:-

let 38.

Another forni of plugging the alternate spaces between the circulating channels 3l is shown in Fig. 7, wherein babbitt or other material 3S is poured into such spaces through openings 39 `and lianoin'erec'ly in place, after which the openings are-tit'ted with suitable screw plugs 40.

I claim as iny invention l. A circulating plate of the character described, provided' with a plurality of spaced fluid-circulating channels having a common inlet and a coininon outlet and passages -intersecting said channels near their ends, said channels and said passages being formed by drilling holes in the plate, plugs fitted in the ends ot' the vchannels and passages, and Eller-pieces extending across said passages and disposcd'n the alternate spaces between said channels, whereby the Huid is diverted in a sinuous course therethrough.

2. A fluid-circulation plate of the character described, having a plurality of angular channels-the parts of which extend inwardly from adjoining edges of the plate and connecting passages intersecting said several channels` and fluid-diverting means in said passages between `certain of said channels, the diverting means in the passage at one edge of the plate alternating with' the diverting ineens in the passage at the adjoining edge to cause a sinuous vflow of the fluid through the channels and passages.

3. A Huid-Circulation plate of the character described having aplurality ot' angular channels,the parts of which extend inwardly from adjoining edges of the plate and "connecting passages intersecting said several channels, and removable plugs -arrai'iged transversely in said passages between 'eert-ain of said channels, the plugs in thepassage at one edge oi the plate alternating with the plugs in the passage at the adjoining edge.

4. A fluid-circulation plate of the character described, having a plural-ity 'of angular or L-sh-apedchannels, theparts of which eX- tend inwardly from adjoining edges of the plate and connectingpassages intersecting the outer portions of said chan-nels, the parts of said angular channels boing'ot progressively increasing length 'from one corner of lhe'plate toward .its diagonally opposite corner.
